6.2.1 DS-CPU3 Configuration Settings
Sensor Configuration
This box lists the sensors that are loaded into the DS-CPU3.
Only the configurations for the ticked sensors are active in the logger. Only
active sensors can have their configuration altered from this window.
The fields can be changed by selecting the desired sensor from the Sensor Configuration box, clicking on
the appropriate field with the mouse and making the necessary changes. Remember that any changes
will not become effective in the datalogger until you have clicked
[Update] to send the updated
configuration to the logger.
Logging Rate
This specifies the time interval in minutes. This is not the sampling rate. The sampled data is averaged
over a period of time defined as the Logging Rate. This is a continuous rolling average.
Alarm Setpoints
It is possible to set up to six different alarm setpoints, depending on the sensor selected.
The DS-CPU3 logging program does not support configurable alarm reset
setpoints. These are hard coded. The DS-4483 however does allow fully
configurable trigger and reset setpoints.
Callback on Alarm
The DS-CPU3 can automatically call up an associated telemetry base (such as HydroTel 2000) if an alarm
setpoint is triggered for any sensor. The base can then respond to the callback and unload any
associated logged data.
Logging Enabled
This setting determines whether the selected sensor is to have its samples logged. In most cases this
would be enabled.
Rain Event Mode
If selected, rainfall will be logged in event mode, that is, rainfall data will only be logged when rainfall
occurs. If this option is not selected, rainfall data will be logged periodically regardless of whether any
rainfall has occurred.
